When Should Physiotherapy Start After ACL Surgery?

Physiotherapy after ACL reconstruction typically begins within the first few days after surgery, sometimes even before you leave the hospital. Early rehabilitation focuses on protecting the graft while restoring critical baseline function.

Why early rehab matters

The first 2–6 weeks after ACL surgery are crucial for: - Controlling swelling and pain - Restoring full knee extension - Reactivating quadriceps muscle - Progressing weight-bearing safely - Preventing joint stiffness

Delays in early rehab are strongly linked to poorer long-term outcomes, including persistent quadriceps weakness that can last months.

What happens in the first sessions

Your physiotherapist will typically assess: - Range of motion (especially extension) - Swelling - Muscle activation - Gait pattern - Pain levels

Then guide you through gentle exercises: quad sets, heel slides, controlled weight-bearing, and safe mobility work.

The bigger picture

ACL rehabilitation is a 9–12 month journey. The early phase sets the tone for everything that follows — including whether you can safely return to sport.
